Strong Storms and Heavy Rainfall Threats; Dangerous Heat for Southern Plains into the Southwest

Thunderstorms, some severe, will impact areas of the Plains into the Midwest today. Rainfall can be locally heavy as well from these storms with isolated instances of flash flooding. Monsoonal flow will enhance rainfall across the Four Corners into the central Rockies today. Meanwhile, summer heat continues for the southern Plains, Southwest into southern California. Read More >

Strong El Niño events impact the spring precipitation across southeast New Mexico, resulting in 100% to 132% of the long term average precipitation. However, there is a significant decrease from DJF precipitation for strong El Niño's (ranging from 177% to 239% of normal). Results for Climate Division 7  indicate that 1992 was an unusually wet year for Roswell and likewise for 2007 in Carlsbad.

 

A description of the graphs is located at the bottom of the page.

 Percent of Longterm Average for all El Niño Events = 122% , for strong El Niño Events = 132%

Precipitation values for 3-month periods during 18 El Niño Events since 1949-50 are plotted with respect to the long term precipitation average, listed to the right of the graph.  The precipitation totals for each 3-month period are plotted above or below each bar.  Years for which the El Niño Event was considered to be strong are colored in dark green.  "M" represents a 3-month period with missing data. Finally, the percents of long term normal for all El Niño events and for the strong El Niño events are listed below each graph.
